If one wants more than the 7 RM and doesn't figure he needs the 7 RUM there is always the 7mmX300 Win Mag. This wildcat has many really good features not the least of which is cheap brass available everywhere. It will equal the 7 STW ballistically and do it with less powder. I am not familiar with this 7mm LRM, but if one is bound to the 404 case then there is always the Dakota..........me personally I like and have hunted and harvested animals with the 7X300 Win and the 7X300 Wby and the Win seems to be the most for the least of all the big 7s I've played with. I also built and hunted with a 7X68 Imp 30 Deg, it is identical to the 300 Win case in capacity and one helluva lot more expensive and difficult to find.........no real advantage there.
Do we need this new big 7, probably not..........I sure as hell don't need it at 4 bucks a pop for brass and I have a 7 RUM and a 7 RM and several other smaller 7s, all of whom wear a buck a pop or less brass, which I find much less objectionable. This cartridge was designed for one purpose only along with the 26 Nosler and that is to make money for Nosler........PERIOD. There were no unfilled niches that these 2 just naturally snuggle into, they are superfluous in the extreme !!!
And really guys.........who gives a rat's ass what dia 8mm REALLY is in thou, we all know it as .323 and have since 1905...........man I get tired of these nit pickers......"7mm isn't REALLY .284 and 8mm isn't REALLY .323 and 6.5mm isn't REALLY .264 and 6mm isn't REALLY .243".........who gives a sh!t, for the purposes of ballistic discussion these are the accepted nominal diameters of the different metric calibers. You don't have to like it or agree with it, but it is what it is, so learn to live with it, or find a new hobby. Guess what 44 ain't .440 either it's .429 and 38 is really .357.............it ain't just the metric system that is confusing and filled with misnomers.
